CLAYTON D. COLLEY, OF COEBURN, VIRGINIA.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 759,674, dated. May 10,1904.

Application filed September 22, 1903. Serial No. 174,177. (No model.)

To all w/wm it may concern:

Be it known that I, CLAYTON D. CoLLnY, a citizen of the United States,residing at Goeburn, in the county of Wise and State of Virginia, haveinvented a new and useful Wrench, of which the following is aspecification.

This invention relates to implements of the class known as quick-actionwrenches, and has for its object to simplify and improve devices of thischaracter; and the invention consists in certain novel features ofconstruction, as hereinafter shown and described, and specified in theclaims.

In the drawings illustrative of the invention, in which correspondingparts are denoted by like designating characters, Figure 1 is asectional side elevation of one of the improved wrenches. Fig. 2 is asectional detail of the movable jaw, and Fig. 3 is a rear view of themovable jaw detached.

The improved implement comprises a stock 10, preferably with a handle 11at one end and terminating at the other end in a laterally-extendedstationary jaw 12 and with spaced transverse ratchet teeth 13 on therear side, as shown. Slidably disposed upon the stock is a movable jaw14, having extensions 15 16, extending, respectively, in advance of itsface and lower sides, as shown. The extension 15 is provided withinternal ratchet-teeth 17 adapted for engagement with the teeth 13 whenthe outer or free end 18 of the movable jaw is tilted away from the jaw12 or when the strain is applied, and thus lock the movable jaw to thestock, while at the same time the movable jaw can be quickly released byreversing the tilting movement. The movablejaw memher is provided with acavity 19 for supporting a spring 20, bearing against the inner face ofthe stock to maintain the movable jaw yieldably in operative positionwith the teeth 17 in engagement with the teeth 13. The extension 16 iscurved outwardly, and the stock 10 is provided with a sleeve 21,slidable thereon and provided with a socket for the extension 16 andhaving a curved rear Wall 22, corresponding to and engaging the curvedouter surface of the portion 16, as shown is Fig. 1. By this simplearrangement the movable jaw member 14:, with its connected sleeve 21,may be freely moved upon the stock 10 in one direction by slightlypressing the outer end 18 of the movable jaw 14 toward the stationaryjaw 12, or by tilting the movablejaw upon the stock to compress thespring 20 and release the teeth 17 from engagement with the teeth 1 3;but the movable'jaw will be instantly locked rigidly in engagement withthe stock when pressure is applied in the opposite direction to themovable jaw, as will be obvious.

When the movable jaw member is tilted to release it, the curvedextension 16 will move freely longitudinally for a short distance in itssocket in the sleeve 21 and upon the curved surface 22 and then carrythe sleeve with it in its sliding outward movement along the stock. Thepresence of the sleeve does not, therefore, interfere with the action ofthe movable jaw when the latter is being set to the nut or other object;but when the strain is applied the sleeve instantly becomes an importantfactor in the action of the implement as the curved portion 22 receivesthe rearward thrust of the extension 16 and divides the strains with theteeth 17 and 13.

The wrench is thus materially strengthened at a very slight addition tothe weight and expense.

The parts will preferably be of steel and may be of any required size toprovide for the production of various sizes of wrenches.

Having thus described the invention, what I claim is-- 1. A wrenchcomprising a stock terminating in a laterally-extended jaw and providedwith spaced transverse ratchet-teeth on the rear side, a movable jawslidably disposed upon said stock and provided with an extension inadvance of its face side having spaced teeth for engagement with theteeth of said stock and with an extension disposed in advance of theopposite side and-curved outwardly, and a sleeve slidably disposed uponsaid stock and having a socket to receive the curved extension of saidmovable jaw, substantially as described.

2. A wrench comprising a stock terminating in a laterally-extended jawand provided with IO sion of said movable jaw, and a spring between saidmovable jaw and the front side of said stock, substantially asdescribed.

In testimony that I claim the foregoing as my own I have hereto afiixedmy signature in the presence of two witnesses.

CLAYTON D. COLLEY.
